I've seen this error with Mellanox ConnectX cards and OFED 1.2.x with all versions of OpenMPI that I have tried (1.2.x and pre-1.3) and some MVAPICH versions, from which I have concluded that the problem lies in the lower levels (OFED or IB card firmware). Indeed after the installation of OFED 1.3.x and a possible firmware update (not sure about the firmware as I don't admin that cluster), these errors have disappeared.
